By combining Self-Organizing Map (SOM), Learning Vector Quantization (LVQ), and Gaussian Mixture Model (GMM) methods, the posterior probability of the various land cover components were estimated for each pixel as a means of sub-pixel analysis. The estimation of impervious surface and the differentiation of urban vegetation grass versus woody tree coverage the main objectives of this paper. Overall, the output estimates compared favorably with those obtained using higher spatial resolution aerial photograph and IKONOS satellite image and traditional hard classification techniques as independent reference.

Sub-pixel estimation of urban land cover components with linear mixture model analysis and Landsat Thematic Mapper imagery / S. Lee in International Journal of Remote Sensing IJRS, vol 26 n° 22 (November 2005)

The relative effectiveness of two different endmember sets was also compared. The interior endmember set consisted of the median pixel value of the training pixels of each land cover and the exterior endmember set was the extreme pixel value. As a means of accuracy assessment, the resulting land cover estimates were compared with independent estimates obtained from the visual interpretation of digital orthophotography and classified IKONOS imagery. Impervious surface estimates from the Landsat ETM showed a high degree of similarity (RMS error (RMSE) within approximately + 10 to 15%) to that obtained using high spatial resolution digital orthophotography and IKONOS imagery. The partition of the vegetation component into tree vs grass cover was more problematic due to the greater spectral similarity between these land cover types with RMSE of approximately + 12 to 22%. The interior endmember set appeared to provide better differentiation between grass and urban tree cover than the exterior endmember set. The ability to separate the grass vs tree components in urban vegetation is of major importance to the study of the urban/suburban ecosystems as well as watershed assessment.

A housing-unit-level approach to characterizing residential sprawl / J. Hasse in Photogrammetric Engineering & Remote Sensing, PERS, vol 69 n° 9 (September 2003)

A multi-temporal land-use/land-cover dataset for Hunterdon County, New Jersey is utilized to measure new housing units developed between Time 1 (1986) and Time 2 (1995) for five traits defined as "sprawl" in the planning and policy literature : (1) density, (2) leapfrog, (3) segregated land use, (4) accessibility, and (5) highway strip. The resulting housing-unit sprawl indicator measurements are summarized by municipality to provide a "sprawl report card". The analysis provides a new direction in sprawl research that addresses sprawl at the atomic level, captures the temporal nature of urban growth, and provides measures that are potentially useful to planners addressing sprawl.
